Lemmy.world has released an official response.
instances need to be constantly online under the same domain to receive new posts. you can't really host an instance from your home without some kind of tunnel or ddns setup, and you surely can't host one from a potentially metered mobile connection.
Does ActivityPub not have retry with back off like email? Mail will try to be delivered for a few days before the sender gives up.
it depends on the implementation. lemmy does have something similar but it's not as aggressive as email and in the peak reddit migration times it wasn't uncommon to have un-federated replies and posts from all the instances being overloaded.
also that queue is stored in memory so if the server dies or gets updated or otherwise restarts it won't bother with old stuff
